Layer and Data Descriptions

22 Apr Layer and Data Descriptions

A reference layer is a visual overlay that can be placed over the base map. A reference layer may be turned on or off (displayed or not displayed) by the user or overlaid on top of another reference layer. Information in a reference layer is not used to generate reports or analysis of a redistricting plan. Rather, the overlay contains information to which the user may refer when drawing a redistricting plan. For example – the user may refer to city council boundaries for purposes of alignment to new supervisorial district boundaries.

The following reference layers are available within the redistricting software:

Current Supervisorial District Boundaries

Communities (cities, unincorporated areas, and community areas within City of Los Angeles)

Los Angeles City Council District Boundaries

Supervisors’ Place of Residence (shown in RDU only)

School Districts

U.S. Congressional Districts

State Senate Districts

State Assembly Districts

May 2009 Special Election Results for Judy Chu and Gil Cedillo, California 32nd Congressional District

2010 General Election Results for Kamala Harris and Steve Cooley, State Attorney General

2010 Primary Election Results for Kamala Harris and Rocky Delgadillo, State Attorney General

To access the reference layers from the redistricting software, click on the right arrow to the left of the screen, after entering the “Create” tab.
